s'ronivr OIL-ANCHOR.

To all whom it may concern:

Be it known that I, FREEDOM W. J AGKSON, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Storm Oil-Anchors, of which the following is a full, clear, and exact description, referencebeing had to the accompanying drawings. 3

This invention relates to devices of the type that are known to the maritime profession as sea anchors and "which, as is known to those skilled in thisv art, are used for the purpose of enabling aboat or similar vessel to ride head to the sea, .thereby to prevent the boat from being swamped through exposure to a heavy sea striking on the beam, quarter, or stern, the anchor serving to keep the boat head-on to the sea, in

which condition it is best able to ride the waves. I

It is the object of this invention to provide a device of this kind which is capable of being collapsed into a small space, thereby facilitating the stowing of the same under the seats'or thwarts of a boat or Within a similar contracted space; to provide a I device of this kind which is particularly well adapted to supply oil to the. water for the purpose of quieting or smoothing down the waves; also to provide a construction which will permit a device of this kind to be conveniently hauled in after the necessity for its use has passed. I

A further and more general object of the invention is to provide a deviceof this kind which, while simple and relatively inexpensive of production, is markedly efficient in operation.

In the drawings forming part hereof,Figure 1 represents a ,view, partly in section,

showing m invention in operationin con nection wit a boat; Fig. 2a plan view of the boat and device shown in the preced ng figure; Fig. 3 an enlarged perspective view of the anchor proper; Fig. A a central, longitudinal section through the anchor; Fig. 5 a sectional detail corresponding'to the line 5-5 of Fig. 4; and Fig. 6 a perspective view of the anchor showing the same collapsed for the purpose of stowing the same within a limited space.

Describing by reference characters the various parts illustrated herein, 1 denotes the body of the sea anchor, which body is preferably of canvas and is frusto-conical in Specification of Letters, Patent. Pat ted 17,1914 Application filed May as, 1914. v Serial No. 241,419.

shape. For convenience of description, the

reduced end of this body will be considered as the bottom and the enlarged end as the top, it beingunderstood, however,

that these terms are employed merely for COHVSIIIGIICG of description and without limitlng the body to any particular position. At its enlarged end, the canvas body is folded and stitched around a .metal ring 2,.

for three purposes, namely :to keep'the enlarged end of the body expanded; to furnish the weight requisite to sink the anchor be low the surface or disturbed water .ofthe sea; and also to provide means cooperating to enable the boat to. be anchored thereto. At its lower or reduced end, the canvas body 1 is provided with a pair of opposed gromet holes 3, which are adapted to receive a bail 4 to which a' tripping line 5 may be attached, to permit-inverting the anchorand' hauling it in with a minimum of resistance. At a suitable distance from its bottom or reduced end, the body 1 is provided with a suitablenumber of gromet holes 6. and, in

the space between the gromet holes 3 and 6, there is inserted an oil reservoir 7, ,which is preferably frusto-conical in shap'e'to enable ,it to fit within the lower or reduced 1' 11, which is rove through the gromet holes- 6, in the manner indicated in Figs. .4: and 5. Atits upperor enlarged end, thebodyis provided with'a series of gromet holes 12, three such holes being shown .andsaid holes being adapted to receive a bridle or span 13.

With the parts constructed as described, the operation will be readily understood. Assuming that the receptacle 7 is filled with oil and a suitable riding-line 14. connected to the bridle, the petcock 8 may be opened sufiiciently to permit of the gradual escape of the oil and the anchor be dropped overboard and the line 14: paid out. The anchor, owing to the weight of the ring 2, will sink beneath the tops of the waves and into the smooth water therebeneath,as represented in Fig. 1. The escaping oil will follow a path substantially as indicated by the broken, irregular lines 15, and this oil will operate in the well known manner to smooth the waves around the boat 16, enabling the latter to ride in comparatively smooth water and without danger of swamping.

It will be observed that the gromet holes (5 are distributed evenly or symmetrically around the circumference, and with respect to all diameters, of that portion of the body 1 in which they are located. As theanchor is dragged through the water in a submerged condition, the water shoots in small streams through these openings, which streams are distributed practically evenly about the body. The passage of the streams through these 0penings-which, in the embodiment shown herein, are contracted by the lacing 11opposes a frictional resist ance to the drag of the anchor through the water, thereby greatly increasing the ethciency of the anchor in minimizing the draggingof the attached boat. The distribution of these openings around the circumference of the anchor prevents the anchor from rotating, as it would readily do if a single opening were provided or if openings were provided extending only around a part of the circumference of the body. When desirable, the anchor may be hauled aboard easily by pulling uponthe tripping line 5, which reverses the direction of the anchor and enables it to be hauled on board with its reduced end pointing to the boat in which position it will oppose the least pos sible resistance to its movement through the water,

In Fig. 6 I have shown the manner in which the anchor may be collapsed. to facilitate stowing the same in spaces of limited area, as beneath the thwarts of boats. The oil receptacle 7 forms a closure for the reduced end of the body 1 and causes all the water that may flow through said body to take the path of frictional resistance offered by the gromet holes 6. 7

By the invention disclosed herein it will be evident that I have produced a storm oil anchor which, when dropped overboard from a life boat, motor boat, yacht, or other vesselcin distress, will not only serve to keep said vessel head on to the waves, thereby preventing the swamping of the vessel and thus saving the lives of the occupants, but one which will maintain to windward a body of oil which will be distributed in accordance with the requirements and which will insure the smoothing of the waves in and about the boat which rides to leeward of the anchor. It will be evident that, tl'irough the use of my invention, such disabled craft can ride in comparative safety until such time as the storm has abated or the boat and its occupants have been picked up.

Having thus described what I claim is 1. A device of the character described comprising a hollow tapered body of col lapsible material, said body having in the reduced portion thereof an oil distributing receptacle and provided. with gromet holes at opposite ends of said receptacle, there being a lacing applied to the gromet holes adjacent the enlarged end of the receptacle and a bail applied to the gromet holes at the reduced end of the receptacle, said body having at its enlarged end a metallic ring and provided, adjacent to said ring and between the same and the receptacle, with aplurality of gromet holes, a bridle attached to the last mentioned gromet holes, and a tripping line connected to said bail.

A device of the character described comprising a hollow tapered body of collapsible material, said body having in the reduced portion thereof an oil distributing device and provided with a plurality of gromet holes adjacent to said device and be tween the same and the enlarged end of the body, a lacing applied to said gromet holes and serving to retain the distributing de vice within the body, means for submerging the body, and means whereby a riding line my invention may be connected to the enlarged end of J said body.

in testlmony whereof, I hereunto aflix my signature in the presence of two witnesses.
